Ceph scalability and high availability

To understand Ceph scalability and high availability, let's first talk about the architecture of traditional storage systems. Under this architecture, to store or retrieve data, clients talk to a centralized component known as a controller or gateway. These storage controllers act as a single point of contact for a client's request. The following diagram illustrates this situation:

Ceph scalability and high availability

This storage gateway, which acts as a single point of entry to storage systems, also becomes the single point of failure. This also imposes a limit on both performance and scalability while introducing a single point of failure, such ...
